IMPROVEMENT IN REMOVABLE CALKS FOR'HORSBSHOES.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

lBe it known that I, EDWARD 'WHLTEHEAD, of Gincinnati, Hamilton county, Ohio, have invented a new and useful Removable Oalk for Horseshoes; ,and do hereby declare the followingto be a full,`elear, and eX- aet description thereof, reference being had to the aoeompanying drawings, making part of this specification.

This invention consists in providing the removable ealks with screw-threaded stems or Shanks, which are inserted in shiftable clips, having lips that are engaged over the top of thelhorseshoe proper, and by simply screwing said stem or shank home, so as to impinge against the bott-om of the shoe, the elip and call; are maintained securely in position, so as to prevent any accidental displacement of the same.

In the accompanying drawings- Figure 1 visv a perspective view of a horseshoe, having my improved ealks attaohed, the view showing the under side of the shoe, and having one of the calks detached;

Figure 2 is a transverse section of the shoe, showing a. number of the ealks in position, and one of them in the act of being attached; and

Figure 3 isa vertical-section of a modified form of my shiftable clip.

A represents a horseshoe of ordinaryconstruction, and

B are a number of shiftable clips, having lips b b', that are adapted to engage around the outer and inner edges ofthe shoe, and bear upon the top of the same, as shown in iig, 2.

rEhe clips have screw-threaded apertures U, for the.

reception of the screw-threaded stems or Shanks d, of the removable calks l).

The clips that are to be attached near the toe of the shoe are somewhat longer than those which are to be applied near the heel ofthe same, so as t-o correspond with the width of the shoe at those parts.

The clips are attached to the shoe in the following manner: y

rlfhey are rst applied. to the shoe near the heel of the same, in the oanted position shown in iig'. 2, so as to cause the lip l1' to engage around the innerfedge' of the shoe. After this, the clip is brought down to a level position, and shifted along to its proper place upon the shoe, which act causes the lip b to engage around the outer edge ofthe shoe, and the oalk being ynow screwed into the lip, so as to cause its shank to impinge against the bottom of the shoe, serves to maintain the parts securely in position.

, In order to enable the elip to turn more freely upon the shoe when in its eanted position, the under side ot' said clip may be recessed, as shown at b in fig. 3, and

for the heavier class of horses, may have an upward eXtension, e, provided with a set-screw, f, which, engaging over the shoe after the application and attachment of the clipkas above, holds the clip securely to its place.

rlhese calks should have somewhat of an outward flare,so as to give as broad a bearing-surihce as possible upon the roadway.

These caiks will not only prove serviceable in slippery weather, but they will also be useful when the horse is driven over' wooden-paved streets.

I claim herein'as new, and of my invention,

l. The shiftable vand double-lipped clip B b b C, when used in connect-ion with the detachable and screw-threaded calk I) d, substantially as herein described, and for the purpose set forth.

2. In combination with the elements of the preceding clause, the extended lip e and set-screwf, snbst-antially as set forth.

In testimony of which invention,I hereunto set my hand.

Vit-nesses EDWARD \VHITEHEAD.
